This invention of improvements in-gas producers has reference to gas producers of the kind in which the blast is delivered to the center of the fire.

The invention has for its object to enable the distribution of the blast to be controlled from the exterior of, and whilst the producer is in operation so that regulation of the rate of gasiflcation over the whole or any part of the fire bed may be effected. i

In a gas producer as referred to, in accordance with this invention, there is combined with the central duct or tuyere and the superposed blast directors or deflectors, often called distributorsorblast hoods, a valve or valves operable from the exterior of the producer to regulate the areaof the passageor passages between the upper end of the central duct or tuyere and the adjacent deflector and/or between the deflectors themselves.

The valve or valves is or are preferably of the sleeve type. l

In order that the invention, the object and nature of which has been set forth, may be particularly described and ascertained, reference will now be made to the constructional embodiment illustrated in the accompanying drawings, in which:

Fig. 1 is a vertical sectional view of a gas producer in which the invention is utilized;

Fig. 2 is a detail vertical sectional view, upon a larger scale, showing a modification of the invention; and

Fig. 3 is a detail view, of the valve op erating screw, associated parts being shown in vertical section.

In the drawings, a gas generating chamher which contains solid fuel is shown at 5, being provided with a cover 6 and with a hopper-shaped base portion? for directing the ash into an ash pan '8. 11-is a central duct or tuyere and 12, 13, and 14 are superposed blast deflectors or directors. These parts are all arranged as ordinarily. 'lVithin the central duct or tuyere 11 there is arrangeda sleeve valve 15. This valve 15 is mounted on one end of a vertically disposed and endwise movable rod 16, the otherendof which is mounted on one end of a lever 17 of the first order. Thislever 17 is mounted on a hearing 18 and is connected at its other end wlth operating means comprising a handwheel 19 and screw and nut 20. By rotation of the hand-wheel 19, the valve 15' is raised or lowered and the area of the passage between the upper end of the central duct or tuyerell and the adjacent deflector or di-.

rector 12 is decreased orincreased.

In Fig. 3, where a portion of the operating means is shown somewhat. more in detail, it will be noted that the connection between the lower end portion 20 ofthe screw and the lever 17 is effected by an opening 21 formed in the lever through which the screw 20 extends, there being considerable clearance between the opening and. the screw. Nuts 22 and 23 with sphericalsurfaces are thread.

ed upon the screw so. as to engage the lever 171113011 its top and bottom surfaces. In this manner a flexible andiadjustable connection is provided.

It will be understood that other means than a. hand-wheel and gearing as illustrated and described may be employed for the purpose of operating thevalve 15. I

In Fig. 2, I have illustrated one means for controlling the passage between deflectors 12 and 13in addition to controlling the passage between 'tuyere 11 and deflector 12. In this instance,;a sleeve. valve 24 slides vertically within the central opening in the deflector r2, being adapted whenraised to more or less completely close the passage between the deflectors 12 and 13. The valve 24 may be mounted and moved'independently ofthe valve 15 by means which may or may not be more or less identical with that illustrated for the valve 15, or, if desired, it may be arranged as'here illustrated to move with the valve 15, at a slower rate, thatlis, at a rate proportioned. to the smaller passage to be controlled. To this end, I may employ a pair of rods 25, 25, connectedat their upper ends tolugs 26 on the sleeve 24 and at their lower ends to levers ,27 pivoted at 28 to the rod 16 and having pin and slot connections with lugs 29 attached at diametrically opposite points to the inner. wall of the tuyere 11. :The relative ratesof motion as between the valves 15 and 24 may, of course, be varied by changing the points of pivotal connection between the rods and the levers 27.

Having thus described my invention, I claim:

1. In a gas producer, a gas generating chamber adapted to contain solid fuel, a fluid duct extending upwardly thereinto, a conical blast deflector mounted upon and spaced from the upper end of said duct, a valve carried by said duct adapted to regulate the area of the passage between the upper end of the duct and said deflector, and actuating means for said valve operable from the exterior of the producer.

2. In a gas producer, a gas generating chamber adapted to contain solid fuel, a fluid duct extending upwardly thereinto, a conical blast'deflector mounted upon and spaced from the upper end of said duct, a sleeve valve slidable upon said duct adapted to regulate the area of the passage between the upper end of the duct and said deflector and actuating means for said valve operable from the exterior of the producer.

3. In a gas producer, a gas generating chamber adapted to contain solid fuel, a fluid duct extending upwardly thereinto a conical blast deflector mounted upon and spaced from the upper end of said duct, a valve carried by said duct adapted to regulate the area of the passage between the upper end of the duct and said deflector, said valve being mounted upon one end of a rod positioned within the duct, and a lever operable from the exterior of said chamber and operatively connected with said rod.

4. In a gas producer, a gas generating chamber adapted to contain solid fuel, a fluid duct extending upwardly thereinto, two superposed conical blast deflectors attached to the upper end of said duct, there being a central connecting air passage between said two deflectors, a valve carried by said duct adapted to regulate the area of said passage, and actuating means for said valve operable from the exterior of the producer.

5. In a gas producer, a' gas generating chamber adopted to contain solid fuel, a fluid duct extending upwardly thereinto, two superposed conicalpblast deflectors at tached to the upper end of said duct, said lower blast deflector having a central opening therethrough, and a sleeve valve slidable within said opening and cooperating with the upper deflector to regulate the area of the passage between the two deflectors, and actuating means for said valve operable from the exterior of the producer.

6. In a gas producer, a gas generating chamber adapted to contain solid fuel, a fluid duct extending upwardly thereinto, two superposed conical blast deflectors attached to the upper end of said duct, the lower one of saiddeflectors having a central opening therethrough, a valve to regulate the area of the passage between the upper end of the duct and the lower deflector, a second valve to regulate the area of the passage between the two said deflectors, and means operable from the exterior of said chamber for manipulating said valves simultaneously.

7. In a gas producer, a gas generating chamber adapted to contain solid fuel, a fluid duct extending upwardly thereinto, two superposed conical blast deflectors attached to the upper end of said duct, the lower one of said deflectors having a central opening therethrough, a sleeve valve mounted upon and slidable with respect to said duct for regulating the area of the passage between the upper end of the duct and the lower deflector, a second sleeve valve mounted in said central opening of the lower deflector for regulating the area of the passage between said two deflectors, and means operable from the exterior of the producer for manipulating said valves simultaneously.

8. In a gas producer, a gas generating chamber adapted to contain solid fuel, a fluid duct extending upwardly thereinto, two superposed conical blast deflectors attached to the upper end of said duct, said lower deflector having a central opening therethrough, a valve for regulating the are:

of the passage between the upper end of the duct and the lower deflector, a second valve to regulate the area of the passage between said two deflectors, and means operable from the exterior of the producer for manipulating said valves simultaneously at different rates of speed.

In testimony whereof I hereunto affix my signature.
